Do you know if there's a (substantial) speed difference between cuda and opencl for nvidia cards?

Re: Algorithm optimizations (reversing steps)

I somehow don't get your point - what do you mean by 're-reverse'? *imho*, you'd have to reverse (reverse ~1 round, in case of MD5) for every hash you want your input to be found. After doing this, you've to sort all reversed hashes. This is the initial cost. Now you just compute 3/4 MD5's and compa...

Re: Algorithm optimizations (reversing steps)

You'd have a fixed initial cost when reading a hash the first time - You could write already-reversed hashes to a cache file, as usual sorted so you can directly memcpy() it. You need a file somewhere anyways if you want to implement a restart option. You also could implement an option to supress th...

Re: That is when C++ sucks

yeah, if you test with latest intel processors, intel compiler will probably produce the best optimized code. But does this really matter for you? I don't know about GPGPU, but the GPU speed shouldn't be affected by this, as compiling this is up to CUDA, isn't it? Btw lol@intel compiler not being ab...

Re: That is when C++ sucks

Why do you need to spend the whole day compiling boost? I remember me doing a build of boost under linux 32bit with gcc, and it took just ~1-2hours building, but nothing complicated to start the build :P
Why are you using the Intel compiler anyway? Just use gcc for all platforms => done :P

Character generation algorithm

Hi, I'm currently programming an FPGA for hash cracking (MD4 for 160 bits input, optimized and pipelined runs at a speed of ~150MhZ, each clock a hash, without comparing and input generating 5/clock) and I'm in search of a way to feed my hash routine with input. This should be mostly for mixedalphan...
